Upgrade freeradius from version 3.0.16 to 3.0.21

Hi, I'm new to freeradius and was tasked with upgrading Freeradius on ubuntu . Right now we are on version 3.0.16 and we would like to upgrade to version 3.018. I have searched around and can't seem to find any article or link on that process. Do we just run apt update and apt --list upgradable then apt--only-upgrade install freeradius, I have already backed up all the files in /etc/freeradius Please help. Thanks.
